Bailey - Chief Engineer} Radiator Tubes Following our recent discussions with Messrs. Holt and Stark of Kynochs, kindly note they are proceeding with manufacture of Radiator Tubes in Copper, of similar size and design to the American samples we loaned them, i.e. 4" long x .267" dia. body .006" wall and 134 bulge. Under existing arrangements they are making these with the waterway .040", but will notify us very shortly if they can produce such Tubes giving a waterway of .060". Personally I still feel that if we can possibly do so we should adhere to the .060" waterway as we are still having a large number of blocks thrown on the Scrap Heap by the Repair Department which seem to have silted up.
